* When all the action-channels for a group are hidden (i.e. their related bones are not visible), the group in question is also not drawn. This helps reduce clutter. (slikdigit funboard request)
* When a group has no channels belonging to it, the expand icon/button isn't drawn for that group.
Also checked all other uses of text->lines.first to make sure the assumption isn't made elsewhere.
Added 2 more checks for text->lines.first when converting text buffer to objects.
* Action FrameProp was checking if the string was true, not that it contained any text.
* Added GameObject.getVisible() since there is already a getVisible
* Added GameObject.getPropertyNames() Needed in apricot so Franky can collect and throw items in the level without having the names defined elsewhere or modifying his game logic which is stored in a separate blend file.
Edited Game engine docs to note that the matrix will need to be transposed if used with Mathutils.Matrix()
Edited "Collision" button since ray-sensor also uses collision.
To take advantage of this feature, you must have a mesh with
relative shape keys and shape Ipo curves with drivers referring
to bones of the mesh's parent armature.
The BGE will automatically detect the dependency between the
shape keys and the armature and execute the Ipo drivers during
the rendering of the armature actions.
This technique is used to make the armature action more natural:
the shape keys compensate in places where the armature deformation
is uggly and the drivers make sure that the shape correction
is synchronized with the bone position.
Note: This is not compatible with shape actions; BLender does
not allow to have Shape Ipo Curves and Shape actions at the same
time.
This patch introduces two options for the motion actuator:
damping: number of frames to reach the target velocity. It takes
into account the startup velocityin the target velocity direction
and add 1/damping fraction of target velocity until the full
velocity is reached. Works only with linear and angular velocity.
It will be extended to delta and force motion method in a future
release.
clamping: apply the force and torque as long as the target velocity
is not reached. If this option is set, the velocity specified
in linV or angV are not applied to the object but used as target
velocity. You should also specify a force in force or torque field:
the force will be applied as long as the velocity along the axis of
the vector set in linV or angV is not reached. Works best in low
friction environment.
* Nothing indicated - is not helpful, and very annoying with occluded geometry with high poly meshes, sometimes the selection doesn't work 100% of the time and the menu pops up over what you want to select.
* No (correct) camera error doesn't seem to be needed, has been there since rev 2.
NAND controller is an inverted AND controller: the output is
1 if any of the input is 0.
NOR controller is an inverted OR controller: the output is 0
if any of the input is 1.
XOR controller is an exclusive OR: the output is 1 if and only
if one input is 1 and all the other inputs are 0.
XNOR controller is an inverted XOR: the output is 0 if and only
if one input is 0 and all the other inputs are 0.
The NAND, NORT and XNOR controllers are very usefull to create
complementary outputs to start and stop actuators synchronously.
MSCV project files updated.
Level option is now available on all sensors but is only implemented on
mouse and keyboard sensors. The purpose of that option is to make
the sensor react on level rather than edge by default. It's only
applicable to state engine system when there is a state transition:
the sensor will generate a pulse if the condition is met from the
start of the state. Normally, the keyboard sensor generate a pulse
only when the key is pressed and not when the key is already pressed.
This patch allows to select this behavior.
The second part of the patch corrects the reset method for sensors
with inverted output.
Snap to edges and vertice without have to go through faces.
This means you can import floor plans and use the edges as snapping guides and other sort of fun things.
The bounding box test still needs padding though.
Added serious interlacing to movies opened using ffmpeg.
(Other video decoders to be done)
Rational: deinterlacing, if done seriously _has_ to be done
in YUV-space. Since internal interface first converts data
to RGB we are pretty much lost (and fall back to IMB_filtery
in that case).
This patch introduces a simple state engine system with the logic bricks. This system features full
backward compatibility, multiple active states, multiple state transitions, automatic disabling of
sensor and actuators, full GUI support and selective display of sensors and actuators.
Note: Python API is available but not documented yet. It will be added asap.
State internals
===============
The state system is object based. The current state mask is stored in the object as a 32 bit value;
each bit set in the mask is an active state. The controllers have a state mask too but only one bit
can be set: a controller belongs to a single state. The game engine will only execute controllers
that belong to active states. Sensors and actuators don't have a state mask but are effectively
attached to states via their links to the controllers. Sensors and actuators can be connected to more
than one state. When a controller becomes inactive because of a state change, its links to sensors
and actuators are temporarily broken (until the state becomes active again). If an actuator gets isolated,
i.e all the links to controllers are broken, it is automatically disabled. If a sensor gets isolated,
the game engine will stop calling it to save CPU. It will also reset the sensor internal state so that
it can react as if the game just started when it gets reconnected to an active controller. For example,
an Always sensor in no pulse mode that is connected to a single state (i.e connected to one or more
controllers of a single state) will generate a pulse each time the state becomes active. This feature is
not available on all sensors, see the notes below.
GUI
===
This system system is fully configurable through the GUI: the object state mask is visible under the
object bar in the controller's colum as an array of buttons just like the 3D view layer mask.
Click on a state bit to only display the controllers of that state. You can select more than one state
with SHIFT-click. The All button sets all the bits so that you can see all the controllers of the object.
The Ini button sets the state mask back to the object default state. You can change the default state
of object by first selecting the desired state mask and storing using the menu under the State button.
If you define a default state mask, it will be loaded into the object state make when you load the blend
file or when you run the game under the blenderplayer. However, when you run the game under Blender,
the current selected state mask will be used as the startup state for the object. This allows you to test
specific state during the game design.
The controller display the state they belong to with a new button in the controller header. When you add
a new controller, it is added by default in the lowest enabled state. You can change the controller state
by clicking on the button and selecting another state. If more than one state is enabled in the object
state mask, controllers are grouped by state for more readibility.
The new Sta button in the sensor and actuator column header allows you to display only the sensors and
actuators that are linked to visible controllers.
A new state actuator is available to modify the state during the game. It defines a bit mask and
the operation to apply on the current object state mask:
Cpy: the bit mask is copied to the object state mask.
Add: the bits that set in the bit mask will be turned on in the object state mask.
Sub: the bits that set in the bit mask will be turned off in the object state mask.
Inv: the bits that set in the bit mask will be inverted in the objecyy state mask.
Notes
=====
- Although states have no name, a simply convention consists in using the name of the first controller
of the state as the state name. The GUI will support that convention by displaying as a hint the name
of the first controller of the state when you move the mouse over a state bit of the object state mask
or of the state actuator bit mask.
- Each object has a state mask and each object can have a state engine but if several objects are
part of a logical group, it is recommended to put the state engine only in the main object and to
link the controllers of that object to the sensors and actuators of the different objects.
- When loading an old blend file, the state mask of all objects and controllers are initialized to 1
so that all the controllers belong to this single state. This ensures backward compatibility with
existing game.
- When the state actuator is activated at the same time as other actuators, these actuators are
guaranteed to execute before being eventually disabled due to the state change. This is useful for
example to send a message or update a property at the time of changing the state.
- Sensors that depend on underlying resource won't reset fully when they are isolated. By the time they
are acticated again, they will behave as follow:
* keyboard sensor: keys already pressed won't be detected. The keyboard sensor is only sensitive
to new key press.
* collision sensor: objects already colliding won't be detected. Only new collisions are
detected.
* near and radar sensor: same as collision sensor.
* OB prefix is needed when specifying the object for the Message Actuator, this is very bad since other object fields in the BGE dont need this prefix - a real fix would need do_versions to keep old files running.
* RotationMatrix was all nans if the rotation vector axis was 0,0,0, Changed so in this case just return a matrix that doesn't rotate anything,
spent some angry hours to find these issues, maybe this will save others the hassle ;)
This patch adds the ability to specify a falloff radius in the Wave modifier.
Currently only linear falloff is supported.
Thanks to Michael Fox for the patch!
* For 2D filters, don't require opengl 2.0 but just the extensions,
so it works on computers without full 2.0 support too.
* In debug mode, don't print memory statistics for preview render.
Shape Action are now supported in the BGE. A new type of actuator "Shape Action" is available on mesh objects. It can be combined with Action actuator on parent armature. Only relative keys are supported. All the usual action options are available: type, blending, priority, Python API. Only actions with shape channels should be specified of course, otherwise the actuator has no effect. Shape action will still work after a mesh replacement provided that the new mesh has compatible shape keys.
GLEW
====
Added the GLEW opengl extension library into extern/, always compiled
into Blender now. This is much nicer than doing this kind of extension
management manually, and will be used in the game engine, for GLSL, and
other opengl extensions.
* According to the GLEW website it works on Windows, Linux, Mac OS X,
FreeBSD, Irix, and Solaris. There might still be platform specific
issues due to this commit, so let me know and I'll look into it.
* This means also that all extensions will now always be compiled in,
regardless of the glext.h on the platform where compilation happens.
Game Engine
===========
Refactoring of the use of opengl extensions and other drawing code
in the game engine, and cleaning up some hacks related to GLSL
integration. These changes will be merged into trunk too after this.
The game engine graphics demos & apricot level survived my tests,
but this could use some good testing of course.
For users: please test with the options "Generate Display Lists" and
"Vertex Arrays" enabled, these should be the fastest and are supposed
to be "unreliable", but if that's the case that's probably due to bugs
that can be fixed.
* The game engine now also uses GLEW for extensions, replacing the
custom opengl extensions code that was there. Removes a lot of
#ifdef's, but the runtime checks stay of course.
* Removed the WITHOUT_GLEXT environment variable. This was added to
work around a specific bug and only disabled multitexturing anyway.
It might also have caused a slowdown since it was retrieving the
environment variable for every vertex in immediate mode (bug #13680).
* Refactored the code to allow drawing skinned meshes with vertex
arrays too, removing some specific immediate mode drawing functions
for this that only did extra normal calculation. Now it always splits
vertices of flat faces instead.
* Refactored normal recalculation with some minor optimizations,
required for the above change.
* Removed some outdated code behind the __NLA_OLDDEFORM #ifdef.
* Fixed various bugs in setting of multitexture coordinates and vertex
attributes for vertex arrays. These were not being enabled/disabled
correct according to the opengl spec, leading to crashes. Also tangent
attributes used an immediate mode call for vertex arrays, which can't
work.
* Fixed use of uninitialized variable in RAS_TexVert.
* Exporting skinned meshes was doing O(n^2) lookups for vertices and
deform weights, now uses same trick as regular meshes.
patch from Shawn Zilbert (enigmatic)
This patch adds the camera data block type to the oops schematic view of the outliner. It also includes a little bit of code cleanup in the oops files.
Snap to cage only in edit mode (respect the edit cage flag of modifiers).
Especially important for subsurf, otherwise, Andy's automerge + snap video doesn't work in current SVN.
This commit fix the following problem in the DPX code:
1) The code always assume a depth of 10 bits
2) The code don't check the file type (Log or Linear)
1. Updated selected restriction to not be so stingy. Snapping on edges and vertices work if they are part of a partially moving face
2. Change depth ordering (which didn't work all the time). Hits are sorted according to 2D distance and then depth, so for overlapping hits, it picks the one in front.
This patch re-assigns the mirrored data to use vertex groups with "mirrored"
names (e.g. L_arm -> R_arm, Leg.R -> Leg.L etc.). Vertex groups with the
"mirrored" names must already exist in the base mesh.
This means that it is no longer necessary to apply the mirror modifier in order
to rig the mirrored data independently.
Thanks to Michael Fox for the patch!
- duplicated script spaces would keep a pointer to the PyObject button list. (causing python errors with negative reference counts when freeing spaces)
- Exiting blender would crash when a UI was open because the ScriptSpaces button PyList was being free'd after python Py_Finalize was called.
---------------------------------------------------
Snappy stuff
* Align rotation with snapping target: rotate the object, aligning it with the target (object mode only - temporarily) (New icon in the header when snap is turned on)
* Snap to different mesh elements (face, edge, vertice): snapping target slide on faces and edge or use exact position of vertice. When using Align rotation with edge snapping, the normal is interpolated as you slide along.
Snaps correctly to derived mesh (sculpt, modifiers, ...) and duplis. In object and edit mode.
NOTE: The snapping code is now based on faces, so even if you're snapping to vertices or edges, it will not work on meshes without faces. This might change if needed.
(partial because I'll merge all snap code in one fell swoop after the libs are done)
----------------------------------
object: ray - boundbox intersection test
----------------------------------
Small fix to derivedmesh for snapping: don't create origindex for
editmesh derivedmesh since it's not being filled correct anyway.
----------------------------------
Arith:
- axis angle to quat conversion function
- short to float / float to short normals conversion function (eventually, we could go over the go and replace copy/pasted code everywhere)
- ray triangle intersection (to complement the line triangle intersection function)
View:
- viewray / viewline (get near plane point under mouse and ray normal/far point)
Particles:
- extract viewline from brush_add function
By Fabrice Tiercelin
This enables rotation angles of more than 180 degrees to result in the same rotation applied to the object (the result used to be clamps between -180 - 180 of the initial rotation).
The patch had to be modified to deal with IPO keys properly
Baking would split non-planer quads in an unpredictable way, which is fine for rending but game engines often use a fixed order (0,1,2), (0,2,3) or (1,2,3) (1,3,0).
Added an option to use a fixed order when baking.
view: noclip version of int and float projection. Also project from behind the view's position and return coherent values for near clipping
transform: use the above functions for 2d center and helpline drawing
NOTE: the result for centers behind the camera (in perspective) isn't 100% perfect in the case of rotations because they always use the centered view vector as rotation axis and not the one aligned with the 2d center. Changing this would not be desirable anyway. At least it's predictible now.
* python Blender.GetPaths() - absolute=0 wasnt working
* BLI_cleanup_file and BLI_cleanup_file were treating the // prefix as a duplicate path, now ignores //
* BLI_convertstringcode was removing the trailing slash from a path
(tested these path functions didnt mess up with some of the peach files and with pointcache)
button input didnt
work. narrow down this test to the part of the pydriver module init that uses a blender textblock as a module. This should
should reload the pydriver dict whenever the "EnableScriptlinks" state changes. but for now working numbuttons is priority.
This adds redcode (the file format of RED one, R3D) support to blender.
Seems to work fine with the footage I found on the web, but keep in
mind, that because of the unoptimized nature of libopenjpeg, frame
decoding isn't that fast.
It is also a rather challenging task, to make 4k-float-footage realtime :)
Some more Bmesh custom data functions and
structures. This still does not do anything
yet because the various conversion functions
don't bother making use of the new custom data
functions. Hooking them up should be fairly
simple though.
Also note that the custom data code is mostly
copy/pasted from the existing custom data
functions for editmode with a few modifications.
Duplicating code like this isn't nice, but I
felt it was better to keep things for Bmesh
'standalone' for the moment and take only what is
immediatly needed instead of creating
a tangle of interdependant code.
Notes:
- edgehash.c still has some weirdo code causing warnings on lines 80 and 117
i.e. if (v1<v0) v0 ^= v1 ^= v0 ^= v1;
- material.c (in pyapi) apparently doesn't seem to be making use of some functions for glossy stuff
Now that new allocator is in place, Custom Data
can be effeciently added to BMesh. The plan is to
make all data not directly related to topology
Custom Data and allow callers to decide precisely
what information a mesh should have in order to
make the best tradeoff between memory usage/speed.
Right now not much to look at, just some structure
definitions and commented out code. More to come
soon...
Added a new pooling allocator for Bmesh based upon
the pool allocator availible in the Boost C++ library
as described here:
http://www.boost.org/doc/libs/1_34_0/libs/pool/doc/concepts.html
Each pool allocates elements of a fixed size, so every
element type in a mesh gets its own pool. For instance
verts occupy a different pool than edges. Each pool
is comprised of multiple arrays of a fixed size and allocating
/freeing elements is simple as removing or adding a head
to a linked list. Since the list of free elements is interleaved
throughout the unused space in the arrays, the overhead
for storing the free list is only 1 pointer total per pool.
This makes building/destroying bmesh structures much faster
and saves quite a bit of memory as well.
Originally the only way to run scripts automatically was with scriptlinks, which could be disabled for loading untrusted blend files.
Since then PyDrivers and PyConstraints would run even when G.f&G_DOSCRIPTLINKS was disabled.
Gensher, Theeth and Ianwill agree its acceptable to reuse the flag for other areas python runs automatically.
PyNodes still have no way to be disabled, (todo before 2.46a)
Shouldn't crash any more in the case that
a) invalid video options were selected
and
b) audio multiplexing was active
[#13311] video_stream NULL when writing ffmpeg
(did'nt crash for me though, but added extra protection :) )
Bevel tool was hanging on certain geometry where the edge
to be beveled was shared by two faces that had more than
one edge in common and caller was not checking return
status of Bmesh eulers. Fixed.
glitch when typing in / would ask the user to make a new directory. the last shash was being removed, then the "" path didnt exist and
asked to create it.
the maximum number of objects (255) wasnt being checked, added a check before baking.
also changed bakeing to use G.scene->base rather then G.main->objects since these can be in other scenes, from linked
groups, or used only by python so they should not be used for baking. it also meant having a domain in 2 scenes would fail with an error.
Nils, could be good to have a dynamic number of bakeable objects.
* [#13394] Sequencer: if internal strips have handles selected, dragging the metastrip changes the meta length
* Extend did not work correctly on metastrips when the nested seq's are out of the meta's frame range, added an argument to seq_tx_get_final_left/right
that returns the frame clipped by metastrip(s) if any.
a script error with a script that has an interface would not stop the interface from running again immediately, causing an annoying
error message loop.
Bug #13277, reported by Juho (bebraw) Vepsalainen (thanks!) - a typo made pynodes w/o input socket definitions fail with an out of range error when accessing the output sockets in the script.
* scene.object.context and scene.object.selected had broken get_item
funcs so scene.object.context[i] returned the wrong object.
* aligning the view to an object (numpad*key), did not disable the
ortho view grid.
* long standing problem where opening a relative image would fail with
no message. BLI_convertstringcode was returning a path with /../../'s
that need to be cleaned before the path could be read, the path was also
invalid from unix shell so its not a blender path reading problem.
* python api render() would clamp the endframe to a short.
* python api's render() and renderAnim() would not render compositing because the name they gave to RE_NewRender was NOT G.scene->id.name, added comments to
G.scene->id.name
Patch from Jean-Michel Soler (with slight modifs)
Small BPy feature to help script writers deal with armatures and vertex groups (calls the bone heat method to create and assign groups)
Instead of making it an exception compared to other objects which
don't draw z-buffered either, it now draws without lighting in the
wire color like it did before.
Force proportional editing flag off in object mode.
While it didn't have any effect on objects themselves, it could display the falloff mode (Smooth) in the header. The bug was purely cosmetic.
* when check_valid_nurb_u/v fails, no curve is allocated or drawn.
* knotsu/v could be NULL but some functions didn't check for this, make sure this is checked for everywhere.
* The interface didnt change check the order when the bezier u/v flag was set, added functions clamp_nurb_order_u/v that takes into accound the number of points and the bezier u/v flag.
When a bone in a mirrored chain wasn't named properly, it would leave the head or tail in an invalid state.
Now it applies the mirror to connected joints that are mirrored.
fixing [#11362] Blender.Draw.Image() method does not clip properly
also return silently on zero zoomlevel rather then raising an error, only raise an error on negative values.
Fixes
[#12106] Memory leak in sequencer (>10MB/frame)
in parts: inner contents of meta strips are freed up after calculation
making more room for the cache.
Actually have to think of a mechanism, that remembers, which output
frames are asked for and caches only those.
The best rules for stereo rendering are now applied to Blender. Here is the new situation:
1) The focal distance is now settable through the GUI: select the camera (each camera can have a different setting) and go to the camera data (F9): the "Dof Dist" and "Dof Ob" can be used to set the focal distance for that camera. The "Dof Ob" is interesting because it sets the focal distance so that the center this object will appear at the surface of the screen when running the game.
2) The eye separation is automatically set to focal_distance/30, which is considered to be a reasonable value. If you need a different value, you can always use Python scripting.
Notes:
- If you switch camera during the game, the focal distance will also change unless you have set the focal distance by scripting, in which case it overwrites the focal distance setting of all cameras.
- If you don't set the focal distance in the camera data or by scripting, the default value will be used. The default value corresponds more of less to the near clipping plane which means that all the objects will be very far with little 3D effect.
- If you don't set the eye separation by scripting, it is automatically computed as focal_distance/30, regardless on how the focal distance was set.
Transform conversion was resetting constraints when used to calculate orbit center.
This is a tentative fix, it fixes this particular case but maybe not all.
Added proper gear support and fixed some misc errors in the setup of this transformation (negative values hav no effect, so use absolute value and other small things like that)
This fixes:
[#11745] Blender crashes when changing Scenes on Sequencer`s Strips
containing:
- last_seq was set to null by scene-render
- button handling wasn't very robust (didn't check for null)
- REDRAWBUTSSCENE was missing
the problem was that the buttons would use the first nurb if there was no 'lastnu', but the makeknots function only checked for lastnu. this meant the knots would not get re-allocated on
values would be written outside the array.
added checks for a nurbes orderu being larger then pntsu.
This has the same effect as the curve having only 1 point. (its display list is not generated
but it is still added but a dummy displist with zero points is made)
memcpy was also being used where the memory overlaped (probably worked in most cases but this is incorrect and valgrind complained), use memmove
instead.
This fixes: [#11642] VSE: crash with Speed Control and play head
Special sequence update (holding down left mouse button on a strip)
could lead to a crash when using the speed control effect, since
we didn't check properly for valid cfras (and therefore if
TStripElem is null... )
- "Memoryblock free: attempt to free NULL pointer" messages related to the Material node (Add->Input->Material). Deleting it and quitting Blender would bring 2 or 3 of these warnings. Trivial fix (check if NULL) in blenkernel/intern/node.c, though Nodes devs may be interested. Found while testing to fix the following bug:
== PyNodes ==
- Bug #11715 reported by Alexanter Feterman:
http://projects.blender.org/tracker/?func=detail&atid=125&aid=11715&group_id=9
Adding a Dynamic node and setting it to a pynode script would crash Blender if no Material Node (MatNode) was present.
Thanks Alexander for reporting and Brecht for assigning it to me.
Broken in revision 14473
Camera IPO needs a special exception to be done earlier than others, that was removed in that revision.
I added a better comment to make sure nobody removes it again, unless they really understand what's happening.
front and back face test was reversed. This problem still shows up when sculpting from the inside of a mesh, but this
cant be worked around unless its know which faces are visible or not. (tried some different workarounds but this
seems acceptable)
IPO's were not being checked for drivers that linked to bones that were renamed when fixing dependencies after renaming bones. Note: PyDrivers will not benefit from this.
Fixing UV Quad Constraint when cancelling transform. Also, transdata conversion is a bit faster for all UV transforms.
Patch by Cambo, reviewed and revised.
